Watch how much the air speeds up when working the chamber. Also, if you leave slight ridge and don't blend the chamber into the top cut, you can slow down the reverse flow. Then bring the flow in good after .250 lift. Helps power production down low. I get better flow with less work using the SM castings. They also have more metal in them in certain spots than the eddy heads allowing for better shaping of things. The throat is large enough to go to a 2.055 intake valve also, only needs a slight increase to get that 90%.
